A CORPORATION OF MARYLAND DRAFT RIGGING vApplication filed May 7,

This invention relates to railway draft rigging and more particularly toa combined backstop and center filler casting normally adapted for usewitha horizontal yoke and supplemental castings for connection theretoto adapt said combined casting for use with a vertical yoke. e

The principal object of my invention, generally considered, is toprovide a backstop preferably functioning as a bolster *cen- Vterfillercasting and provided with a front face normally adapted to be engaged bya horizontal yoke and rear stop lug portions adapted for connectiontosaid front face and the associated sills of the car for adapting saidcasting foruse with a vertical yoke, said, yoke ,normally extendingbetween the lug portions with the associated follower engaging the frontfaces of sald lug portions.

Another object of my invention is to provide a backstop normally adaptedfor use with a horizontal yoke and means for converting said backstopfor use with avertical yokesaid means being readilyapplied or removed,as desired. e

A further object of my invention ris to provide stop lugs which are`adapted for connection tothe front face of a Istandard back? .isnormallyused with a horizontall yoke for use with a vertical yoke and associatedrear follower, said stop lugs providing abutments for said rearfollower.

Y Other objects and advantages o f the invention relating to theparticular arrange ment and construction of the various parts willbecome apparent as lthe description proceeds. y

Referring to the drawings illustrating my invention, the scope whereofis defined by the appended claims:

Figure 1 is a partial plan and partial horizontal sectional view ontheline 1-1 of Figure 2, showing one embodiment of my convertible backstopwith portions of the as- ,Mciated sills and other parts of the car.I

Figure 2 is a vertical central Vlongitudinal DVtional view oftheembodiment shown 1n Figure 1n 1928. Serial No. 275,729.

Referring to the drawings in detail, like parts being designated by likereference characters, a backstop and bolster center filler casting 1 isshown with side walls 2 connected to associated center or draft sills 3by a plurality of rivets 4. Said backstop preferably, but notnecessarily, functions as a bolster center ller casting, the associ-V ofthe patent to lright #1,458,792, datedv June 12, 1923. For improving thestrength of said front wall, the side portions 10 thereof preferablyextend diagonally to meet the front portions of the side walls 2 of thecasting. The rearwardv portions of the side walls are preferablyconnected by a rear wall 11, which is desirably alined with the webs ofthe rear bolster plates 5, as illustrated. Said casting is alsodesirably formed with a bottom wall 12 and a top wall 13, said wallspreferably alining with the corresponding flanges of the center sills 3,which 'in the present embodiment are channel shaped in section withoutstanding flanges.

Extending upwardly from the bottom wall 12 of the casting is a hollowcylindrical or thimble portion 14 which provides a king pin aperture 15and the `bottom bolster cover plate is similarly apertured, as shown inFigure 2. For rigidifying the casting and tying the front'and rear wallstogether and to the thimble portion 14, a horizontal wallor web 16 isprovided whichV preferably extends in the plane of the rcenter line ofdraft from the front wall9 vto-thevrear wall 11, surrounds the thimbleportion 14 and extends between and connects the side walls 2. Forfurther tively narrow reinforcing web, as illustrated most clearly inFigure 2. The side or outer flanges or webs 17 preferably convergeslightly toward each other and flare downwardly to connectwith thebottom wall 12 and upwardly to connect with the top wall 13', asillustrated, whereby they form tie webs between the front, rear, top andbottom walls of ,the casting. 5

The casting is further tiedA togetherA transversely by an intermediateweb 18 which eX- tends between the side walls and top andbottom walls ofthe casting and connects said walls together and to the thi'mblepoi'tionl`4 of said casting, an aperture 19 being provided above the thimbl'eportion', 'and that portion of the wall defining the upper part of saidaperture being formed with a horizontal flange portion 20. Suchcastingas been `inst described functions admirably for use with ahorizontal yoke as well 'as a bolster center filler casting, as will beunderstood.

lt is sometimes desirable to use 'a casting identical with the ba'ckstopvcasting heretofore described, but instead of using :a horizontal yokeand Farlow attachments, to use a vertical yoke and rear draft lugs forconnecting with the associated rear follower. In the patent to lYrightheretofore lreferred topa backstopis there disclosed which is "adaptedfor use with either a `if'eiti'cal or horizontal yoke but which for thatpurpose is necessarily reversed in position and involves inte,- gral lugportions which add to the weight :of said casting, withoutperforming-any useful function, except when employed with a verticalyoke. lnaccordance with the .present invention, I accomplish the same purposetendedby the patent referred to without 'add- 7 ing unnecessary weightto the casting and withoutniaking it necessary to reyerse said castingfor adapting it for use with a vertical yoke.

ln accordance with `my invention, therefore, I employ `draft lugcastings or auriliary members 21 which have side webs 22- normallyconnected to the associated sills 3 by a plurality of rivets 23, thefront edgesof said walls or webs 22 being formed with inwardly extendingweb portions 24 vwhich function as stop lug portions Iforengagement withthe movable element of an associated draft Vgear or rear follower V25,indicated diagrammatically in dot 'and dash lines, assof ciated with thevertical yoke, indicated diagrannnatically Yby dot and dash lilies at26. A preferred construction of said stop l'lug castings 21 involvesapproximately horizontal web or flange portions 27eXtending rearwardlyfrom the stop web 24, vone at the upper edge, which 'preferably tapersto 'the rear end of fthe side wall portions '22, and two intermediatethe upper and lower edges ofsaid casting, The lower edge of'said castingin the present embodiment is slightly `spaced relation to the slopingupwardly from the front to the rear of the casting and is bordered by acorresponding flange 28, which preferably tapers like the upper flange27. The upper and adjacent langes or webs 27 and the lower and adjacentflanges 28 and 27, respectively, are connected by the side wall portions22 vof the casting at their outer edges and the intermediate flanges orwebs 27 are connected by inner portions 29 at their inner edges, saidinner wall portions preferably extending'from the inner edges of thestop web portions 24 to the front face or web 9 of the associatedba'ckstop casting 1, where they are flanged inwardly or toward eachother, as in dicat'ed 'at 30, to provide connecting lug or flangeportions, lpreferably fory receiving an attaching rivet 'or othersuitable connecting means 31.` The connection between the web portions29 and 30 is lpreferably rigidi'lie'd by means of a triangular gussetportion 32.

From theforegoing description, taken in connection with the accompanyingdrawings, it will be seen that l have devised a backstop casting whichis normally adapted for use with a horizontal yoke but which, Ywithout'being oversize f'or without necessitating reversal, may be convertedfor use with `a vertical yoke by the connection to its front face of apair of stop lug or vertical yoke adapter castings, which are alsoformed for rigid connection with the associated sillsof a car.

'claimt 1. An adapter casting comprising a vertical wall portion rformedfor Yconnection to an associated sill, a vertical wall portion eX-tending at right angl'esthereto and adapted to functionas a rear stoplug, horizontal walls ktherebetween for rigidifv- 'ing the construction,a vertical wall extending from the 'edge of 'said stop lug portionfarthest 'from the first-inei'itioned connecting wall portion 'anddiyerging slightly from said wall portion, and means connecting adjacentportions of said vertical walls, the edge of said diverging wallfarthest from said connecting 'wall bein-g bent and contin- 'uedtransversely away from said connecting wall and adapted for connectionto la backstop casting.4
